摘要

The present invention provides a method for manufacturing a cylinder block (1) of an air-cooled engine, the step of producing a cylindrical nickel foam (7) in close contact with the outer peripheral surface of the inner mold (3) of the casting mold cylinder block (1), Adding and mixing titanium powder to the nickel foam (7) (S2), heating the nickel foam (7) mixed with titanium powder to remove moisture (S3), and forming the nickel foam (7) into a mold And a step (S4) of injecting aluminum alloy molten metal into the molds 3 and 5 in a non-pressurized state after the insertion between the mold 3 and the outer mold 5. According to this, it is possible to manufacture a cylinder block which is lightweight and has excellent wear resistance.
